Abstract

The transmission of electromagnetic waves through the samples of the composite material containing Fe–Si–Nb–Cu–B alloy particles with a size of up to 50 µm was studied. The dependences of the transmission and reflection ratio on the magnetic field were measured at frequencies from 12 to 38 GHz. The dependence of the effective magnetic permeability on the magnetic field was determined, and the complex refractive index was calculated. The frequency dependence of maximum values was investigated for the real and imaginary parts of this index.

摘要

研究了电磁波通过包含尺寸高达 50 µm 的 Fe-Si-Nb-Cu-B 合金颗粒的复合材料样品的传输。在 12 至 38 GHz 的频率下测量了透射率和反射率对磁场的依赖性。确定了有效磁导率对磁场的依赖性，并计算了复折射率。针对该指数的实部和虚部研究了最大值的频率依赖性。
